Abstract
The utility model discloses an online black-washing multi-layer filter sand-filtering column purified-water filter which mainly comprises a sand-filtering column. The filter is characterized in that the front part of a filtered water outlet valve III on a water inlet pipe outside the purified-water filter is provided with a filtering flow-limiter; and inlet water passes through a water distributor at the upper part of the filter through a water inlet valve I, so that the water uniformly passes through a first filtering layer filled with active carbon, a second filtering layer filled with anthracites, a third filtering layer mechanically filled with manganese sand and a fourth filtering layer mechanically filled with fine quartz sand so as to form a filtering system, and then filtered water enters a water applied position via the filtered water outlet valve III. Via a black-washing water inlet valve II and from the bottom of the filter, black-washing inlet water in the water inlet pipe outside the purified-water filter sequentially passes through the fourth filtering layer mechanically filled with fine quartz sand, the third filtering layer mechanically filled with manganese sand, the second filtering layer filled with anthracites and the first filtering layer filled with active carbon, so as to form a black-washing system, and then black-washing water is drained to a sewer pipe through a black-washing outlet valve IV. The purified-water filter disclosed by the utility model is reasonable in structure and convenient to operate.
Description
Technical field
The present invention relates to a kind of online backwashing multilayer filtrate sand filtration post water-purifying filter.
Background technology
The household filter purchasing price of market sale now is high, there is no the backwash setting, and the user rinses difficulty, and more the renew cartridge cost is high, and therefore, general resident installs and uses seldom.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, provide a kind of cost lower, have and filter and backwashing function, easy to operate, simple in structure, the online backwashing multilayer filtrate sand filtration post water-purifying filter that water quality is good.
Technical scheme of the present invention is: a kind of online backwashing multilayer filtrate sand filtration post water-purifying filter, mainly contain the sand filtration post, it is characterized in that: be provided with filtered water inlet valve I and filter out water valve III, backwash water intaking valve II and backwash outlet valve IV on the inlet pipeline of described water-purifying filter outside; Be provided with the filtration current limiter filtering out water valve III front portion; Water inlet is passed through filter top water-locator through the water intaking valve I, filter course, second that water evenly is equipped with active carbon by first successively are equipped with Wu the filter course of Uu coal and the 3rd, manganese layer of sand, the 4th are housed the filter course that machine is joined tiny quartz sand is housed, form filtration system, drainage outlet valve III after filtration enters the water place.
Above-mentioned a kind of online backwashing multilayer filtrate sand filtration post water-purifying filter, it is characterized in that: described backwash water inlet is by backwash water intaking valve II, inherent filtration device bottom is equipped with that manganese layer of sand, second are equipped with anthracitic filter course, first is equipped with the filter course of active carbon successively through the 4th filter course that the tiny quartz sand of grating is housed, the 3rd, form backwashing system, backwashing water enters downcomer line through backwash outlet valve IV.
The present invention compared with prior art has the following advantages.
(1) technical solution of the present invention is reasonable in design, and structure is tightly played, and cost is lower.
(2) supporting in technical solution of the present invention have a backwashing system, obviously improved and used water quality.
(3) easy and simple to handle, easy to maintenance, but all Self-operating and maintenances of general user;
(4) filter course long service life, the filter cycle of operation is long.
(5) the filtration current limiter be provided with in valve III front portion, during filtration, flow is little, uses large flux enhancement repercussion effect during recoil, can automatically change.
(6) the present invention can be widely used in the industries such as resident family, residential quarter centralizedly supply drinking-water, food and drink, bathing, carwash etc., be specially adapted to rural area, small towns with natural water, as scenery with hills and waters, lake water, well water, as the area application of drinking water source, has extensive promotion prospect.
Fig. 1 is filtration system schematic diagram of the present invention.
Fig. 2 is backwashing system schematic diagram of the present invention.
The A-A generalized section that Fig. 3 is Fig. 2.
In figure, 1, the inlet valve I; 3, flowing water Valve III; 2, backwash inlet valve II; 4, backwash outlet valve IV; 5, activated carbon filter layer; 6, anthracite filters; 7, filtration with manganese sand; 8, quartz sand filtration; 9, base; 10, bracing frame; 11, current limiter; 12, water-locator.
The specific embodiment
Now, by the specific embodiment and accompanying drawing, the present invention is further described as follows.
A kind of online backwashing multilayer filtrate sand filtration post water-purifying filter, mainly contain the sand filtration post, it is characterized in that: be provided with filtered water inlet valve I 1 and filter out water valve III 3, backwash inlet valve II 2 and backwash outlet valve IV 4 on the inlet pipeline of described water-purifying filter outside; Be provided with and filter current limiter 11 filtering out water valve III 3 front portions; Water inlet is passed through filter top water-locator through water intaking valve I 1, make filter course 5, second that water evenly is equipped with activated carbon by first that filter course 6 without the Uu coal, the 3rd manganese layer of sand 7, the 4th are housed the filter course 8 that machine is joined tiny quartz sand is housed, drainage outlet valve III after filtration enters the water outlet pipe network.Wherein, active carbon is graininess, and anthracite is 0.5mm-0.8mm, manganese sand 0.5-1.0 mm, quartz sand 0.3-0.5mm, 0.6-1.2mm; According to 2:2:2:4, filled, the filter course total height is that 350mm(is small-sized).The filter inner bottom part is provided with bracing frame 10, and top is provided with water-locator 12, and filter bottom is located on base 9.
Above-mentioned a kind of online backwashing multilayer filtrate sand filtration post water-purifying filter is characterized in that: described backwash water inlet is by backwash water intaking valve II 2, through the 4th, machine is housed successively bottom the inherent filtration device and joins the filter course 8 of tiny quartz sand, the 3rd
MachineManganese layer of sand 7, second are equipped with anthracitic filter course 6, first is equipped with the filter course 5 of activated carbon, forms backwashing system, and backwashing water enters downcomer line through backwash outlet valve IV 4.
From accompanying drawing 1,3 with foregoing description, can know and see: the present invention relates to two Filter valves, two back flush valves.Relate to while filtering, only describe Filter valve; While relating to backwash, back flush valves is only described.In this two process, two valves not describing are in closed condition (each file is identical).
Turbidity, effectively catching that the present invention can effectively reduce water remove removing ferro in water, manganese, suspension, visible impurity, silt etc., can absorbing harmful substances in water effectively removal.Its experiment the results are shown in following table 1
Table 1. experimental result (take running water as example):
| Project | Water inlet | Water outlet | Clearance | Remarks |
| Turbidity | 1 | 0.65 | 35% | ? |
| Oxygen demand | 〈2.62 mg/L | 2.0mg/L | 23% | ? |
| Iron | 0.15 mg/L | 0.0525 | 60.4% | ? |
| Manganese | 0.2 mg/L | 0.13 mg/L | 61% | ? |
| Organic matter | 1.73 mg/L | 0.4mg/L | 23.1% | ? |
| Ammonia nitrogen | 1.54 mg/L | 0.43mg/L | 72% | ? |
| Nitrite | 0.089 mg/L | 0.003mg/L | 96．6% | ? |
Here it should be noted that: the water source difference, filter course height, filtrate are also different.Under normal circumstances, about half a year, backwash is once; Rainy season, water quality inferiority, according to water quality situation after filtering, adjusted the backwash number of times.
